Thanks for the question, the way you would want to do this is to create a copy of one of the surveys so that it becomes the Master survey. You would then export the data from both of the original surveys as CSV files and then import both into the one Master survey.

This article will walk through the process of what you need to know about doing a data import. One thing to note, the responses will lose the response ID that was initially associated with the response and will be re-numbered on import.

Take a look at that & if questions pop up, reach out to us at support@sgizmo.com or via chat for more assistance!

Be excellent to each other,
